Compare to 27.5m and you get a scale of roughly 1:30. The newer Falcon set LEGO released is 90cm long. I found the number I was looking for: 27.5 meters. On the web I found the site of a guy who had built a LEGO Falcon (Cool LEGO site of the week for August 1-7, 1999!) and he had all sorts of factoids that he had discovered while working on his project. The first step was to determine the scale of the Falcon. Which made me wonder, how big would a LEGO Imperial Star Destroyer be if built to a similar scale? After seeing the fantastic new 5000-piece LEGO Millennium Falcon in an earlier GeekDad post, I realized it had to be a scale model because the minifigs actually fit into the Falcon the way they would if both ship and crew were full sized.
